And as the Chineses have many sorts of Learning which these Parts of the World never heard of, so all those useful Inventions which we admire ourselves so much for, are vulgar and common with them, and were in use long before our Parts of the World were Inhabited. Thus Gun-powder, Printing, and the use of the Magnet and Compass, which we call Modern Inventions, are not only far from being Inventions, but fall so far short of the Perfection of Art they have attained to, that it is hardly Credible, what wonderful things we are told of from thence, and all the Voyages the Author has made thither being imploy'd another way, have not yet furnish'd him with the Particulars fully enough to transmit them to view; not but that he is preparing a Scheme of all those excellent Arts those Nations are Masters of, for publick View, by way of Detection of the monstrous Ignorance and Deficiencies of European Science; which may serve as a Lexicon Technicum for this present Age, with useful Diagrams for that purpose; wherein I shall not fail to acqaint the World, 1. With the Art of Gunnery, as Practis'd in China long before the War of the Giants, and by which those Presumptuous Animals fired Red-hot Bullets right up into Heaven, and made a Breach sufficient to encourage them to a General Storm; but being Repulsed with great Slaughter, they gave over the Siege for that time. This memorable part of History shall be a faithful Abridgement of Ibra chizra-le-peglizar, Historiagrapher-Royal to the Emperor of China, who wrote Anno Mundi 114. his Volumes extant, in the Publick Library at Tonquin, Printed in Leaves of Vitrify'd Diamond, by an admirable Dexterity, struck all at an oblique Motion, the Engine remaining intire, and still fit for use, in the Chamber of the Emperor's Rarities. And here I shall give you a Draft of the Engine it self, and a Plan of its Operation, and the wonderful Dexterity of its Performance.
